Dumb question time.

How did you test the original part? I ask because you mentioned hot water testing a replacement part. Can we assume you used this same method on the original?

Is the AAV getting power? Excuse me for asking but you did not mention it so I have to wonder. You say it won't close completely but if it passed the hot water test then wouldn't the problem be electrical?

If you are wondering what's going on inside there are some pretty good pics of a gutted valve in this query from another DIY site. Please be informed, I am not suggesting this guys problem is your problem. His valve might be open or closed or somewhere in between on cold start. I only put this here for purposes of illustration. In fact, I am saving these pics for my own future reference.

You sound like a tinkerer. I thought maybe you would like to explore fixing the original before resorting to other methods.
